Finding a percentage
This lesson presents finding a percentage by expressing the rate as a decimal and multiplying it by the base.
Thus, we have three important terms to define when finding a percentage
The rate is the percent
The result obtained when a number is multiplied by a percent
The base is the amount you are taking a percent of
For instance,look at the following percent sentence:
40 % of 60 is 24
40% is the rate
60 is the base
21 is the percentage
Example: Find 25 % of 100
25% = 0.25
Using a calculator, 0.25 times 100 = 25
Example: What number is 75% of 200?
75% = 0.75
Using a calculator, 0.75 times 200 = 150
Example: x is 20% of 80.What is x?
20% = 0.20
Using a calculator, 0.20 times 80 = 16
